Application filed March 31, 1914. Serial No. 828,596.

To all whom it may concern:

3 Be it known that I, Jesse ,A. JANns, citizen of the United States, residing at Metropolis, in the county of Massac and State of Illinois, have invented certain new and useful Improvements in Automatic Water- ,Grages, of which the following is a specification. r

This invention relates to attachments for steam generators andithe like, for the purpose of denoting the height of water there- ,in, moreparticularly to devices of this'character in whicha glass or like fragile trans- ;parent material isemployed in which the height of the water is visible,-and has for one of its objectsto provide a simply constructed device whereby in event jof the I VlW of the combined guide'and stop.

breakageof the fragile member of the device, the steam and water will be automatically cutoff and 1 prevented from escaping and held in cutoff-condition until the broken orimpaired portionis restored. j

Another object of the invention isto' provide a simply constructed device of this character 'which may be readily attached to steam generators and like devices of various sizes in which steam or other medium under ,pressure is maintained, and without material structural change n the device or in the generator. I: I

Anotherobjeot of the invention is to pro- .videa simply constructed device which may be arranged in :coactive relation with ordinary glass water gages without material structural-change in the glass supporting portion of the gage. 7

W ith, hesei and other objects in view the invention consists in certain novel features of construction as hereinafter shownand described and then specifically pointed out in the claimsgand in the drawings illustrative 'Qfthepreferred embodiment ofthe inventionFigure ljisanelevation partly in section'of aportion of asteam generator with one of the improved devicesapplied, a per- .tion of 'thefdevicebeinglikewise insection. Fi 2 is a transverse section on the line 22 of 'Fig. 1. Fig. 3 isa'perspective view from beneath of the mainIbalanced valve of the device. Fig. 4 is a detached perspective Corresponding and like parts are referred to in the following description and indioated in all the views of the drawings'by'the same reference characters.

The improved device comprises; coacting casings, each having a plurality of internal valve seats and connected by a tubular mem-' ber of glass or like transparent material or substance, one of the casings adapted to be connected in a generator above the waterline and the other casing connected in the generator below the water-line, so that the level or stage of the water is visible within the glass tube in the ordinary manner of a water gage. The valve casings are precisely alike and the description of one will suffice for both. 7

The body of the casing is preferably formed of two portions 10-11, the portion 10 having a valve seat 12 while the portion 11 is detachably connected to the portion 10 preferablyby'threading as shown at 13, and with a valve seat 14 in its threaded end and communicating at 15 with the interior of the casing portion 10. The casing portion 10 is arranged to be connected preferably by means of a nipple 16 and clamp nut 16,

the liquid under pressure, one wall of which indicated conventionally at 17-. The caslng port1on'l0 is enlarged as represented at 18 between the seat 12 and the nipple connection 16 to provide free circulation for the steam or water, and is likewise provided with an intermediate shoulder 19. A relatively large valve2O is located within the portionlO of the casing and adapted to engage the seat '12 and is provided with a stem 21 extending into the smaller portion of theoasing. The stem 21 is formedwith longitudinal steampassages in its sides, and

is preferably formed triangular asrepresented in Fig. 2, so that the steam or water will-freely pass. Bearing upon the shoulder 19 is'a stop member 22, preferably in spiderlike form, to permit the free passage of V steam orwater, and operates to support one end of a spring 23,the opposite end of the springv bearing against the valve 20. The Jstopmember 22 is formed with passages or lguideways to slidably receive the wings of V the stem21 as shownin Fig. 4.

1 The valve 20 is formed with radiating wings 24: at the side oppositefrom its seat, so that thevalve will not close against the in avsteam generator or like receptacle for p nipple 16v when open and shut off the water 2' or steam, as hereafter explained.

The threaded terminal 25'0f the casing portion 10 where it engages the nipple16 is sufficiently large to permit the valve 20 and itsspring 23 and stop member.-22to be inserted and removed through its" larger threaded end, and likewise to permit the seat 12 to be properly ground.

The portion 11 of the casing-is internallyv threaded to receive the threaded portion'26 ofthe stem 27 of a valve 28 whichis adapted to be engaged with the seat 14 when the" valve stem is operated. Theportion 11 of the casing is provided with the usual cap 29 and turning wheel 30, to enable the valve 28 to be opened and closed from the exterior of the casing. Extending from the stem 27 in advance of the valve 28 is an extension 31 adapted to engage theouter end'of'the stem'21 of the valve 20 when the valve 2-8 is disposedupon its seat. By this means when'the' valve 28 is moved into its inner position the valve 20 Wlll be forced from its seat, the object to be hereafter explained.

Each of the portions 11 of the'casing is provided with a branch 32 and a union device 33 whereby a tubular glass member 34: is coupled to the oppositely disposed casings.

As before stated, one of the casings will be coupledinto the generator 17 below the water-iline while the other casing and its attachments will be coupled into the gen erator' above the water-line, or in position to receive thesteam, which is conducted into the upper end of the glass tube 34,

mal-conditions, the'heightof the water-in V i "the boiler will beaccurately indicated. In

while the water is conductedinto the lower "end 'of the glass tube, the member 34 thus serving the purpose of a water gage in the ordinarymanner.

fThe valves 20,being relatively large and each providedwith one of the springs 23,

-are' forced from their seats by the action of the springs, and the steam or water under pressure permitted to flow equally, around all sides of the valves 20 and thus balance the same and maintain them normally ,in

open position,-and permit the water and steam to fiowfreely into-the opposite-ends 'ofrthe' glass indicator member 34:. Thus, while the generator is operating under'norevent of the'breakage or impairment of the glass member 34 the pressurewill besudjdenly reduced in the portions of the eas- "ings 1011 externally of the valves 20, and the pressure of steam and water will ins'tantly close, the valves 20 and prevent the escape of the steam and water from the generator, and the valves will remaln closed -s'o long as the glass member 34is detached;

- the valves 28' willbefclose'd by rotating the The-valves 20 will not-be disturbed until a new-tube 34 has been disposedin place when wheels 30 to causethemitoengage therseats {1-4. At the same'tirne thev projections 31 willfengagethe stems 21 of the main valves 20 slightly in advance of the-seating of the valves By this the valves 20 will be forced from their seats to a limited extent before the valves 28 are closed, and thus I into the glas's'member 34 as before, the i valves 20 being maintainedjperfectly balanced and permitting the steam" or waterto freely flow, as before stated.

The improved device is simple in construction, can be manufactu red of any suit- "able-material and any required size, and applied without material structural change 'to steamgenerators and like devlces, and

will automatically cut off the water or steam in event of the breakage of'the gage and tube, thus preventing theescape' of steam and water and holding the steam'andwater "ba'ck in the boiler until the gage has been repaired. V c s r Having thus described the invention,what
